Carbon steel elbow is a kind of prefabricated directly buried carbon steel elbow made of high-density polyethylene outer sheath polyurethane foam plastic, which is closely combined with the elbow conveying medium, high-density polyethylene outer sheath, and the polyurethane rigid foam carbon steel layer filled between the elbow and the outer sheath. It is a kind of high-density polyethylene outer sheath polyurethane foam plastic. Just put the elbow after rust removal and anti-corrosion inside the polyethylene sleeve, and inject polyurethane foam in the middle to fully fill the gap between the elbow and the polyethylene sleeve, In the later stage, the elbow, sleeve and carbon steel layer will form a solid whole to achieve the effect of anti-corrosion carbon steel, and then the carbon steel elbow will be formed.
Most carbon steel elbows are processed by pressure, which will lead to plastic deformation of the processed carbon steel elbows.
According to the different processing temperatures of elbows, they can be divided into cold processing and hot processing. The main processing methods of carbon steel elbows are: semi continuous rolling mill: including a steckel mill with one stand and a finishing mill with five stands. On the semi continuous rolling mill, the hot rolling of pipe fittings in the finishing pass is virtually constant from one end of the pipe fittings to the other end; The time between passes on the finishing mill is usually less than 3s. The pipe fitting process is characterized by central segregation of continuous casting thin slab. Eliminating the central segregation of continuous casting thin slab is a key technical problem to further improve the quality of carbon steel elbow pipe fittings. In addition, carbon steel elbow is a kind of elbow that can improve the temperature of heat preservation. It is often used in people’s daily life and has been widely accepted and used. Carbon steel elbow is widely used in building, decoration and pipeline laying, which can ensure the normal and smooth flow of the pipeline.
Carbon steel elbow can be used as roof, door, window, curtain wall, interior and exterior wall finish, handrail, etc. in architecture, and is widely used in the entrance, lobby, middle hall, etc. of type malls, restaurants and hotels. It is also frequently used in Tonggao Hall and Four Seasons Hall, because carbon steel elbow is not only a novel architectural decoration method with high appreciation value. At the same time, because of its specular reflection effect, it can achieve the effect of interacting with various colors and scenes in the surrounding environment. At the same time, with the cooperation of lights, it can also form the highlight part of the glittering and translucent hall, which helps to form the center of interest in the space environment in these shared spaces, and play an embellishment and foil role in the effect of the space environment.
According to the development of the carbon steel elbow pipe fitting industry, new requirements are put forward for carbon steel. Industry insiders believe that the carbon steel industry has a large market capacity, but the competition has not been reduced. The response is to increase scientific and technological development.
For example, the colorful carbon steel technology of some carbon steel manufacturers has made the shiny carbon steel products colorful, filled the domestic gap, and reached the reliability of the same industry abroad. Carbon steel products for construction and decoration include steel sheets, pipes, profiles, various profiled materials and various shapes. There are more steel sheets with a thickness of less than 2mm. In order to prevent the pipes from cooling and shrinking due to ambient temperature and blockage. The heating inductor and heat sensor are combined to form a heating combined sensor to reduce pre heating and reduction, which is very effective not only in the production of large diameter elbow combined sensor, but also in the production process of stainless steel elbow.
